Background: There has been much interest recently in reducing the length of inpatient stay after hip and knee arthroplasty and much of the relevant literature has linked this to minimally invasive surgery. Orthopaedic departments are often under great pressure to reduce inpatient stay in order to increase throughput of patients. However it is incumbent on those of us responsible for patient care to ensure that systems are in place to maintain safety.

Patients and Methods:We looked at a 6 month period of early discharge with a dedicated ‘Accelerated Discharge Team’ (A.T.T.) at our institution. The team consisted of three nurses, two physiotherapists and two ‘technical instructors’. All patients undergoing hip or knee arthroplasty were assessed pre-operatively and post-operatively for admission to the care of the A.T.T. against fixed criteria. Patients were visited at home on the day of discharge and every day until released from the care of the team. 333 patients underwent lower limb arthroplasty during the study period of which 305 (91.6%) were admitted to the care of the A.T.T.

Results: The mean lengths of stay for primary hip and knee replacements were 3.43 and 3.30 days respectively. The mean for revision hip and knee were 5.75 and 3.29 days respectively. 66% (95% C.I. 57%–74%) of patients undergoing primary hip arthroplasty went home by 3 days and 91% (95% C.I. 85%–95%) by 4 days. 73% (95% C.I. 64%–81%) of patients undergoing total knee arthroplasty went home by 3 days and 93% (95% C.I. 87%–97%) by 4 days. The most common reasons for delay were: social reasons or living alone; low blood pressure or haemoglobin level; difficulty walking. Of the 305 patients, 12 (4%) were readmitted to hospital within 6 weeks of discharge, 2 of these patients (1%) were still under the care of the A.T.T. Almost 90% of patients responded to a satisfaction survey. 94.2% of those responding indicated that they would use the A.T.T. scheme again.

Discussion: Other authors have linked early discharge to minimally invasive surgery or to special anaesthetic/ analgesic techniques. It has also been shown that both carepathways and patient education protocols can reduce length of stay. In the year before implementing the A.T.T. the mean stay for primary hip and knee replacements was over 9 days. We were able to reduce this to less than 3.5 days for over 90% of our patients during the study period. This was achieved safely and without any special surgical or anaesthetic techniques. The total cost of the scheme was just under £100 000 for the 6 month period. We estimate that 2000 bed days were saved during the same period. This is cost effective on these terms alone. As well as transferring 12 elective orthopaedic beds to a different department we were able to perform an estimated 75 extra lower limb arthroplasties in the 6 month period.

Aim To review 6 months of early discharge with a dedicated ‘Accelerated Discharge Team’ (A.T.T.) at our institution.

Results The mean length of stay for primary knee replacements was 3.30 days. 73% (95% C.I. 64%–81%) of patients undergoing total knee arthroplasty went home by 3 days and 93% (95% C.I. 87%–97%) by 4 days. Results for hip arthroplasty were similar. Of the 305 patients, 12 (4%) were readmitted to hospital within 6 weeks of discharge. Almost 90% of patients responded to a satisfaction survey. 94.2 % of those responding indicated that they would use the A.T.T. scheme again.
